Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to a method and system for controlling the mouse cursor on a laptop computer. Background Technology

[0002] In confined spaces like high-speed trains, when users need to temporarily use their laptops for work, the space available is limited. For example, each seat on a high-speed train has a small tray table, the size of which is suitable for a laptop, but there's not enough space for a mouse or other items. Therefore, users often have to use the laptop's touchpad instead of a mouse, which is inconvenient for those accustomed to using a mouse. Placing the mouse on the seat or lap negatively impacts both ease of use and comfort. Similarly, there's no space for a mobile phone on the table. In scenarios requiring the use of both a laptop and phone, the phone is typically held in the hand, placed on the seat, or resting on the laptop's C-side. However, about two-thirds of the laptop's C-side is occupied by the keyboard. Placing the phone on the keyboard hinders typing and, given that a typical phone weighs around 200g, can lead to accidental key presses. Placing the phone on the remaining one-third of the C-side is also problematic, as the bottom left and right sides are usually too small to fully accommodate it. The touchpad is located at the bottom center of the C-side. If you place your phone on the touchpad, the phone will be in place without any problem, but it will block the touchpad and directly affect its use.

[0003] The main pain points in this scenario can be summarized as follows: 1. Limited desktop space leaves no room for a mouse; placing the mouse elsewhere negatively impacts the user experience, leading to the common practice of using a laptop's touchpad instead. 2. Limited desktop space also prevents seamless integration between the phone and laptop, hindering usability and increasing the risk of dropping or losing the phone. Therefore, a solution to these problems is needed. Summary of the Invention

[0009] According to a second aspect, embodiments of the present invention provide a method for controlling a mouse cursor on a laptop computer, the method comprising: contacting a laptop touchpad and a capacitive screen of a touch display device, such that the touch display device senses the touch size of the laptop touchpad through the capacitive screen, and displays a touch area of ​​the touch size on the capacitive screen; receiving an operation command sent by the touch display device through a processor, the operation command being received by the touch display device from the touch area through the capacitive screen; and responding to the operation command by controlling the mouse cursor on the laptop screen to perform a corresponding operation.

[0010] Optionally, the step of making contact between the laptop touchpad and the capacitive screen of the touch display device, so that the touch display device senses the touch size of the laptop touchpad through the capacitive screen, includes: monitoring a second capacitive sensing value sensed by the laptop touchpad, and determining whether the second capacitive sensing value is within a second preset range; when the second capacitive sensing value is within the second preset range, determining that the capacitive screen and the laptop touchpad have successfully made contact, and sending a mapping signal through the laptop touchpad so that the touch display device receives the mapping signal through the capacitive screen, and determines the touch size of the laptop touchpad based on the mapping signal.

[0011] Optionally, before monitoring the second capacitive sensing value sensed by the laptop touchpad and determining whether the second capacitive sensing value is within a second preset range, the method further includes: determining whether a handshake matching mode has been entered; if the handshake matching mode has been entered, then the step of monitoring the second capacitive sensing value sensed by the laptop touchpad and determining whether the second capacitive sensing value is within a second preset range is performed.

[0012] According to a third aspect, embodiments of the present invention provide a system for controlling a laptop mouse cursor, comprising a touch display device and a laptop computer, wherein: when the capacitive screen of the touch display device contacts the laptop touchpad, the touch display device senses the touch size of the laptop touchpad; the touch display device displays a touch area of ​​the size of the touch size on the capacitive screen; the touch display device receives an input operation command from the touch area through the capacitive screen; the touch display device sends the operation command to the processor of the laptop computer; the processor of the laptop computer responds to the operation command and controls the mouse cursor on the laptop screen to perform a corresponding operation.

[0017] The technical solution provided in this application has the following advantages:

[0018] The technical solution provided in this application, considering that laptop touchpads are generally based on capacitive touch principles, and touch display devices generally also have touchscreens, which are also generally based on capacitive touch principles, proposes using the touchscreen of a touch display device to replace the laptop touchpad for operating the computer system interface. First, the capacitive screen of the touch display device comes into contact with the laptop touchpad, allowing them to sense each other and thus the touch display device detects the touch size of the laptop touchpad. Based on the sensed touch size, the touch display device displays a touch area of ​​the same size as the touch area on the capacitive screen. The user then performs touch operations on this area, receiving the user's input commands. Next, the touch display device sends the operation commands to the laptop's processor. Finally, the laptop's processor responds to the operation commands, controlling the mouse cursor on the laptop screen to perform the corresponding operation. Based on the solution provided by the embodiments of the present invention, the touch display device can be placed on the touchpad on the C-side of the computer in a confined space, avoiding the problem that placing the touch display device on the touchpad on the C-side of the laptop would block the touchpad and affect the operation of the touchpad, while ensuring the stability and safety of placing the touch display device.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Considering the limited space in application scenarios, such as small desktops with no extra room for a mouse (placing it elsewhere negatively impacts user experience), laptop touchpads are typically used instead. Similarly, there's limited space for a mobile phone; placing it elsewhere hinders seamless collaboration between the phone and laptop, affecting usability and increasing the risk of dropping or losing the phone. This invention proposes using a mobile phone's touchscreen instead of the laptop's touchpad for operating the computer interface. This avoids the problem of the phone obstructing the touchpad when placed on the laptop's C-side, while also addressing phone security and improving the convenience of collaborative work between the phone and laptop. Based on this, the invention provides the following technical solution.

[0030] Please see Figure 1In one embodiment, a method for controlling a laptop mouse cursor specifically includes steps S101 to S104 and steps S201 to S203, wherein steps S101 to S104 are applied to a touch display device, and steps S201 to S203 are applied to a laptop computer, and the specific steps are as follows.

[0031] Step S201: Make contact via the laptop touchpad and the capacitive screen of the touch display device.

[0032] Step S101: By contacting the capacitive screen with the laptop touchpad, the touch size of the laptop touchpad is sensed. The capacitive screen is the capacitive screen of the touch display device.

[0033] Specifically, Figure 2 This refers to the capacitive sensing pattern used in most capacitive touchscreens and laptop touchpads. It's primarily a mutual capacitance scheme, consisting of a transmit channel (TX) and a receive channel (RX). The TX transmit signal and RX receive signal generate a certain amount of capacitance sensing when a finger or object with changing capacitance touches the touchscreen, allowing for coordinate positioning. Capacitive screens are basically made by applying specific processes (printing, photolithography, etching, etc., depending on the touchscreen design) to glass or a particular PET film. Then, ITO (indium tin oxide) or certain special alloys (copper alloys, nano-silver, etc.) are used as the capacitive sensing material.

[0034] HA202300436 should be patterned on glass or film to become a capacitive touchscreen module. The finger acts as a conductor; when the fingertip touches the capacitive screen, an electron exchange occurs between the fingertip and the screen, thus sensing the change in capacitance. This embodiment of the invention considers that the capacitive screen and the laptop touchpad are also conductors, so when they are in contact, they can also sense each other. Therefore, when a capacitive screen is needed to replace the laptop touchpad, this embodiment of the invention places the touch display device upside down on the laptop touchpad, allowing the capacitive screen of the touch display device to contact the laptop touchpad. In this embodiment, the touch display device can be any terminal device with capacitive touch functionality, such as a mobile phone, tablet computer, independent touchpad, or smart wearable device; the principle is the same. This embodiment uses a mobile phone as an example for explanation. For example, placing a mobile phone upside down on the laptop touchpad allows the phone screen to contact the laptop touchpad. When a mobile phone's capacitive screen and a laptop's touchpad come into contact, both will generate changes in capacitance. The mobile phone can then sense the touch size of the laptop's touchpad based on the amount of capacitance it detects, while maintaining the same aspect ratio, and thus determine the size of the laptop's touchpad area.

[0035] Step S102: Display a touch area of ​​the size of the touch screen on the capacitive screen.

[0036] Step S103: Receive operation commands input from the touch area via the capacitive screen.

[0037] Step S104: Send the operation command to the processor of the laptop computer.

[0038] Specifically, after sensing the size of the laptop's touchpad, the phone can display a touch area of ​​the same size on the phone screen, allowing the user to perform mouse operations on this area, such as swiping left, right, up, down, clicking, double-clicking, etc., thus generating operation commands. The phone's processor receives the operation commands input by the user on the touch area through the screen. A pre-established communication connection between the phone and the laptop (either wired or wireless) allows the phone to forward the operation commands to the laptop's processor.

[0039] Step S202: The processor receives the operation command sent by the touch display device. The operation command is received by the touch display device from the touch area through the capacitive screen.

[0040] Step S203: Respond to the operation command and control the mouse cursor on the laptop screen to perform the corresponding operation.

[0041] Specifically, after receiving the operation command sent by the mobile phone, the laptop processor responds to the operation command and controls the mouse cursor on the laptop screen to perform corresponding sliding, clicking and other operations.

[0042] Thus, through the above steps, this embodiment of the invention realizes a solution to replace the touchpad of a laptop computer with the screen of a touch display device. In desktop application scenarios with limited space, the touch display device can be placed on the touchpad on the C-side of the computer, avoiding the problem that placing the touch display device on the touchpad would block the touchpad and affect the touchpad operation, while ensuring the stability and safety of placing the touch display device.

[0043] Specifically, in one embodiment, step S101 above includes the following steps:

[0044] Step 1: Monitor the first capacitance sensing value of the capacitive touchscreen and determine whether the first capacitance sensing value is within the first preset range.

[0045] Step 2: When the first capacitive sensing value is within the first preset range, it is confirmed that the capacitive screen and the laptop touchpad have made successful contact.

[0046] In this embodiment, step S201 specifically includes the following steps:

[0047] Step 3: Monitor the second capacitive sensing value of the laptop touchpad and determine whether the second capacitive sensing value is within the second preset range.

[0048] Step 4: When the second capacitive sensing value is within the second preset range, it is confirmed that the capacitive screen and the laptop touchpad have made successful contact.

[0049] Specifically, taking a mobile phone as an example of a touch display device, in this embodiment of the invention, the step of the mobile phone capacitive screen sensing the size of the laptop touchpad includes two parts. The first part, namely steps one to four, is the process of mutual sensing between the mobile phone and the laptop, the purpose of which is to confirm that they have touched each other, rather than touching other objects such as fingers. In normal usage scenarios, the mobile phone screen is not in contact with the laptop touchpad. Therefore, when the mobile phone capacitive screen and the laptop touchpad are in contact, the capacitive sensing values ​​generated by each other will fall within a relatively specific range. This serves as the condition for the mobile phone capacitive screen and the laptop touchpad to "handshake". The mobile phone continuously monitors the first capacitive sensing value sensed by the capacitive screen. When the first capacitive sensing value is within a first preset range, it indicates that the mobile phone capacitive screen and the laptop touchpad are in contact. This serves as a trigger signal, indicating that the mobile phone and the laptop have successfully "handshaked", triggering the mobile phone to enter the matching stage and begin sensing the touch size of the laptop touchpad. Similarly, in this embodiment of the invention, the laptop continuously monitors the second capacitive sensing value of the laptop touchpad. When the second capacitive sensing value falls within a relatively specific second preset range, the laptop determines that the capacitive screen and the laptop touchpad have successfully made contact, thereby entering the subsequent matching stage, and cooperating with the mobile phone to sense the touch size of its own touchpad.

[0050] Specifically, in this embodiment of the invention, after step four above, the laptop computer performs step five below, and after step two above, the touch display device performs steps six and seven below.

[0051] Step 5: Send a mapping signal via the laptop touchpad.

[0052] Step Six: Receive the mapped signal emitted by the laptop touchpad through the capacitive screen;

[0053] Step 7: Determine the touch size of the laptop touchpad based on the mapped signal.

[0054] Specifically, after the laptop touchpad and the phone's capacitive screen establish a connection, the laptop uses software pre-programmed into the touchpad's firmware to send a mapping signal of the same aspect ratio onto the phone's capacitive screen. The phone then captures the received mapping signal at a corresponding location. The phone's capacitive screen firmware partitions this area to determine the laptop touchpad's touch size and uses the designated area of ​​that size as the touch area to replace the laptop touchpad's touch operation. This achieves the solution of replacing the laptop touchpad with the touch display device's screen.

[0055] Specifically, in one embodiment, step S102 above includes the following steps:

[0056] Step 8: Display the touch area at the top of the capacitive screen, and display the original desktop of the capacitive screen in the area excluding the touch area.

[0057] Specifically, such as Figure 3 As shown in the embodiment of the invention, a mobile phone is used as an example of a touch display device. When the mobile phone senses the touch size of the laptop touchpad, the firmware within the touch chip of the mobile phone's capacitive screen reserves an area at the top of the screen with the same aspect ratio as the laptop touchpad as a touch area. Simultaneously, other areas of the mobile phone's touchscreen undergo UI / UX optimization via system software. The pixels and aspect ratio of the original capacitive screen desktop are displayed in the optimized manner in areas other than the top touch area, allowing the user to continue operating mobile applications. This enables simultaneous mobile phone operation and mouse control, improving the efficiency of collaborative work between the mobile phone and laptop.

[0058] Specifically, in one embodiment, step S104 above includes the following steps:

[0059] Step 9: Send the operation command to the second Bluetooth module through the first Bluetooth module, so that the second Bluetooth module forwards the operation command to the processor of the laptop. The first Bluetooth module and the second Bluetooth module are successfully paired Bluetooth modules. The first Bluetooth module is installed in the touch display device and the second Bluetooth module is installed in the laptop.

[0060] Specifically, in this embodiment of the invention, the touch display device and the laptop computer establish a communication connection in advance via Bluetooth. Operation commands received by the touch display device from the screen are sent to the laptop computer's processor via Bluetooth, thereby enabling the laptop computer to control the movement and clicking of the mouse cursor according to the received Bluetooth signals. Specifically, as... Figure 4As shown, taking a mobile phone as an example of a touch display device, through the pairing and handshake between the mobile phone's capacitive screen and the laptop's touchpad, the mobile phone has already displayed a touch area in the designated top area. At this time, when a finger touches the touch area of ​​the mobile phone screen, it is activated through I... 2 The C interface transmits data to the phone's processor CPU1. Then, data is transmitted between the first Bluetooth module BT1 (connected to the phone's processor CPU1) and the second Bluetooth module BT2 (connected to the laptop) based on the BLE protocol. After receiving the data signal from the phone's touchscreen, the laptop's second Bluetooth module BT2 transmits it to the laptop's processor CPU2. The laptop's processor CPU2 then controls the screen via the screen's EDP or MIPI interface. This completes the entire process of the phone controlling the laptop screen.

[0061] Specifically, in one embodiment, prior to step three above, a method for controlling a laptop mouse cursor applied to a laptop computer further includes the following steps:

[0062] Step 10: Determine if handshake matching mode has been entered. If handshake matching mode has been entered, proceed to Step 3.

[0063] Specifically, considering that users don't actually need to replace their laptop touchpad with a touch display device in real-world applications, but might mistakenly place the touch display device upside down on the laptop touchpad, causing mismatch and inconvenience, this embodiment of the invention adds a function to enable or disable a handshake pairing mode on the laptop side. When the user enables the handshake pairing mode, the laptop will determine if the second capacitive sensing value is within a second preset range. If it falls within this range, a mapping signal will be emitted to coordinate with the capacitive screen to sense the touch size of the laptop touchpad. If the user does not enable the handshake pairing mode, the laptop will not determine if the second capacitive sensing value is within the second preset range, and the touch display device and laptop will not perform a handshake pairing. Even if the user mistakenly places the touch display device upside down on the laptop touchpad, the touch display device will not replace the laptop touchpad with the capacitive screen, thus further improving the convenience of using the touch display device and laptop.

[0064] Based on the above embodiments, such as Figure 5 As shown, the complete process of replacing a laptop touchpad with a capacitive touchscreen is as follows:

[0065] 1. Both the touch display device and the laptop are powered on and Bluetooth is enabled. The touch display device and the laptop are paired via Bluetooth, and the laptop is set to enable handshake pairing mode.

[0066] 2. Place the touch display device upside down on the laptop's touchpad, so that the capacitive screen of the touch display device contacts the laptop's touchpad.

[0067] 3. During the handshake phase, the capacitive screen of the touch display device and the touchpad of the laptop computer read the first capacitive sensing value falling within the first preset range and the second capacitive sensing value falling within the second preset range respectively through the capacitive sensing pattern, so that the touch display device and the laptop computer can successfully handshake and start matching.

[0068] 4. During the matching phase, the touch display device senses the touch size of the laptop touchpad through the capacitive screen, while the laptop touchpad cooperates with the touch display device's sensing. Then, the touch display device generates a touch area of ​​the same size on the optimal area of ​​the capacitive screen (e.g., the top).

[0069] 5. If the touch display device and the laptop are successfully connected via Bluetooth, the touch display device will forward the user's operation commands to the laptop via the Bluetooth module. The laptop's processor will then respond to the received operation commands and control the mouse cursor to perform the corresponding operations.

[0070] Through the above steps, the technical solution provided in this application involves contact between the capacitive screen of a touch display device and the touchpad of a laptop computer, allowing the capacitive screen and the laptop touchpad to sense each other. The touch display device then senses the touch size of the laptop touchpad. Based on the sensed touch size, the touch display device displays a touch area of ​​the same size on the capacitive screen. The user performs touch operations on the touch area, receiving the user's input commands. The touch display device then sends the commands to the laptop's processor. Finally, the laptop's processor responds to the commands and controls the mouse cursor on the laptop screen to perform the corresponding operation. Based on the solution provided by this invention, the touch display device can be placed on the touchpad on the C-side of the computer in confined spaces, avoiding the problem of the touch display device obstructing the touchpad and affecting its operation, while ensuring the stability and safety of the placement of the touch display device. Furthermore, the laptop screen can be controlled via a mobile phone screen instead of the laptop touchpad, and the operation is not limited to the fixed position of the touchpad.

[0071] Furthermore, in this embodiment of the invention, a touch area is generated proportionally in the upper half of the mobile phone's operating interface, using the same aspect ratio as the touchpad. In the remaining visible screen area, the UI graphical interface is optimized for aspect ratios via system software and used for normal operation of mobile applications and the system interface. This allows the mobile phone to control the laptop screen without affecting the normal use of the mobile phone's functions. Devices for controlling screen operation are not limited to mobile phones; any terminal device with Bluetooth and capacitive touch functionality can be used to pair, handshake, and transmit data with a laptop with a customized touchpad sensing pattern, satisfying the application operations of various types of terminals. The system software controls the on / off switch of the handshake pairing mode between the mobile phone's capacitive screen and the laptop's touchpad. The handshake pairing mode can be turned on when the mobile phone needs to control the laptop screen and turned off when not needed, allowing for flexible and convenient control based on user needs.

[0072] like Figure 6 As shown, this embodiment also provides a system for controlling the mouse cursor of a laptop computer. The system includes a touch display device 1 and a laptop computer 2, wherein:

[0073] When the capacitive screen of the touch display device 1 comes into contact with the touchpad of the laptop 2, the touch display device 1 senses the touch size of the touchpad of the laptop 2.

[0074] The touch display device 1 displays a touch area of ​​the size of the touch screen on a capacitive screen.

[0075] The touch display device 1 receives input operation commands from the touch area via a capacitive screen.

[0076] The touch display device 1 sends operation commands to the processor of the laptop computer 2.

[0077] The processor of laptop 2 responds to operation commands and controls the mouse cursor on the laptop 2 screen to perform corresponding operations.

[0078] Specifically, in one embodiment, the touch display device 1 sends operation instructions to the processor of the laptop computer 2, including:

[0079] The touch display device 1 sends operation commands to the second Bluetooth module installed in the laptop computer 2 via the first Bluetooth module installed in the touch display device 1.

[0080] The laptop computer 2 receives operation commands via the second Bluetooth module and forwards the operation commands to the processor via the second Bluetooth module.

[0081] Specifically, the explanation of the above system embodiments can be found in the relevant description of the above method embodiments, and will not be repeated here.

[0082] Specifically, in one embodiment, the system for controlling a laptop mouse cursor provided by this invention also proposes improvements to the laptop touchpad. The capacitive sensing pattern in the laptop touchpad designed in this embodiment includes a symmetrically bent pattern.

[0083] Specifically, such as Figure 7 As shown in (a), most laptop touchpads on the market currently use capacitive sensing patterns, all based on the mutual capacitance principle. Their touch sensing patterns are created by etching and developing strip-shaped copper patterns onto a PCB (printed circuit board). As a capacitive touchpad module, the mutual capacitance sensing pattern basically consists of horizontal and vertical transmitted signals TX and received signals RX. This transmit-receive mechanism locates the position coordinates of a finger or other object that can generate capacitance changes and produces a certain amount of capacitive sensing. However, this invention designs a portion of the capacitive sensing pattern of the laptop touchpad as... Figure 7 The pattern in (b) will receive the last two channels of channel RX, i.e. Figure 7 In (a), channels R9 and R10 are adjusted to four channels, and the distance between the channels is halved. The sensing patterns of these four channels are then routed with "symmetrical bends," i.e. Figure 7 (b) shows R9, R10, R11, and R12. Additionally, the touch chip for the laptop touchpad needs to provide two more channels for the design of the new capacitive sensing pattern. Figure 7 (b) only uses the last four RX channels as an example. In practical applications, the symmetrically bent channels can also be located in other positions of the RX channels, or they can be designed to be located in the TX channels.

[0084] based on Figure 7 The design differences of the sensor graphics of the laptop touchpad in (b), such as Figure 8 As shown, when a laptop touchpad comes into contact with a mobile phone capacitive screen, the resulting first and second capacitive sensing values ​​are more specific, and their ranges are also more unique. When ordinary gestures or objects that generate capacitance changes touch the capacitive screen or touchpad, the resulting first and second capacitive sensing values ​​are unlikely to fall within their corresponding specific ranges. Therefore, this embodiment of the invention uses this specificity as a condition for the two devices to match and interact, further avoiding accidental operations caused by accidental touches.

[0085] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
